Description

BACKGROUND OF THE INVENTION

Field of the Invention

The invention relates generally to apparatus for loading magazine fed firearms with ammunition, and more particularly to an apparatus that facilitates loading rounds from a magazine from a plurality of magazines bundled by a multi-magazine manifold, where in the invented apparatus facilitates easier change from one magazine to a next magazine without taking eyesight off of a target.

Background

Magazines for firearms having a magazine well, as exemplified by the AR-15, vary in size depending on the application. In general military AR rifles typically would hold from about 30 rounds of ammunition up to about to about 100 rounds, depending on the caliber. Normally, the rounds are held in a single removable magazine that is secured in the magazine-well of the receiver. A magazine above about 60 rounds becomes very long and weighty, and the magazine is difficult to be effectively manned by most personnel. If the caliber is 45 or higher, the count can be lower, and the ammunition is instead often fed on a belt or mechanically automated. Civilian AR rifles tend to be limited to smaller magazines, typically holding from 5 to 30 rounds. Legislation in multiple states limits the round count to 10 rounds per magazine.

In the current specification, the term “magazine” is used throughout the specification to be inclusive of the term “clip” and other terms for prepackaged ammunition for firearms. The term “firearm” is used throughout the specification to be inclusive of a barreled weapon, including replicas, novelty firearms, mock firearms, gaming firearms such as paint ball guns, computerized guns, toys guns, pressurized gas propelled guns, and virtual guns that are digital representations.

A problem with a low round count and an automatic firearm, as exemplified by an AR-15, AR-16, Uzi and AK-47, is that with a short burst of fire the entire magazine can be emptied, and as the firearm fires the recoil tends to lift the barrel, especially if the magazine has a small round count. The recoil must be physically countered by the shooter, and can be actually harder to control than a firearm loaded with a larger heavier magazine, because the weight of the magazine helps to offset the recoil. To be armed, the shooter has to replace an emptied magazine with another magazine that contains rounds of ammunition, and the shooter's capability of aligning the magazine with the magazine-well is more difficult as the shooter becomes tired. The magazine-well is approximately rectangular, with a closed front side, a closed back side, an open bottom side and a top side that feeds to the firearm's chamber. The current prior art teaches that magazines can be coupled into groups, not unlike packaging, where the magazines are stacked and sometimes spaced. The prior art is silent on how coupled magazines can be utilized with an apparatus that facilitates their usage.

SUMMARY OF THE INVENTION

The invented apparatus makes it much easier to align and chamber a magazine in the magazine-well, so that changing magazines can be performed without visually disengaging from a target, wherein the magazine is one of a plurality of magazines bundled on a multi-magazine manifold, wherein the multi-magazine manifold can rotate and or can be shifted. An aspect of the invention is that the apparatus includes an adapter that is mounted onto a handguard, where the mount can be directly mounted to the handguard, or fitted onto a handguard rail that is mounted to the handguard. Examples of handguard rails include Picatinny and Weaver rails.

The adapter is made of a durable material, as exemplified as an engineering plastic, a durable plastic, a suitable metal or metal alloy as exemplified by aluminum and steel. The adapter is securely affixed to the handguard rail, nominally to a lower portion of the receiver and forward of the magazine-well. In one variation the adapter includes a beam and fastening elements, as exemplified by one or more locking bolts with hardened steel hex head nuts. The adapter provides a solid platform that won't slip even under heavy recoil.

Another aspect of the invention is that nominally the multi-magazine manifold is a symmetrical device that has a plurality of mounting faces on a side of one or more polygons, wherein a base of a magazine can be secured to a mounting face on the side of the polygon and the base of another magazine can be secured to an adjacent side or an opposing side, the exact configuration being dependent on the size, shape and number of the polygons.

Another aspect of the invention is that the apparatus includes one or more slide rails in connection with the adapter, where at least one slide rail is a vertical slide rail, and the vertical slide rail has a slidable element with a strut assembly that extends rearward toward the magazine well and provides a supporting connection to the multi-magazine manifold. A position of the strut assembly is determinative as to when the multi-magazine manifold, loaded with magazines, can be changed. When the position of the strut assembly is in a magazine is loaded into the magazine well of the firearm, then the multi-magazine manifold is stationary until released, causing the magazine to be ejected. When the position of the strut assembly is out, the multi-magazine manifold can be rotated and or shifted to a next stopping point where a next magazine is aligned beneath the magazine well. Nominally, the orientation of a firearm being fired is upright, and when a magazine is ejected gravity helps move the magazine, the manifold and other movable elements of the invention downward.

The strut assembly provides spatial orientation for a magazine to be withdrawn or inserted in the magazine-well, wherein the strut assembly, mounted on a slidable element moves downward when a loaded magazine is ejected from the magazine-well. The strut assembly is nominally raised to insert a next magazine in the magazine-well.

While in the out position the multi-magazine manifold can be rotated and/or shifted to a predetermined stop, where the next magazine is stopped in spatial alignment with the magazine-well, where the ammunition of the next magazine is properly oriented to be chambered when the next magazine is loaded into the magazine-well.

Another aspect of the invention is that rotation is either in a plane of a side view of the firearm, or rotation is into the page of a side view of the firearm, or rotation is not required. The orientation of the rotation is largely dependent on the configuration the multi-magazine manifold.

Another further aspect of the apparatus is that it can include a horizontal slide rail, wherein the horizontal slide rail is mounted at right angles to the adapter. The horizontal slide rail includes a horizontal slidable element having a rigidly attached vertical slide rail assembly, where the vertical slide rail assembly can include piggy backed vertical rails wherein a second vertical slide rail is coupled to a first vertical slide rail with one or more slidable elements. Movement of the horizontal slidable element and the affixed vertical slide rail assembly is in the z plane, which is into or out-of the page of the side view of the apparatus mounted on a firearm.

Nominally, the horizontal slide rail has two or more z-plane stopping points for shifting the horizontal slidable element. The z-plane stopping points are selected so that at least one of the magazines which is affixed to the multi-magazine manifold is spatially aligned between a right side and a left side of magazine-well. A length of one or more strut elements of the strut assembly is selected so it that extends rearward from the vertical slide rails where the next magazine to be loaded is spatially aligned front-to-back with the magazine-well. Loading does not require that a user visually disengage from a target, as alignment is automatic.

Another aspect of the invention is that the apparatus can include a slidable grip assembly that is attached to the adapter forward of the at least one vertical slide rail. A strong rod, one that can support recoil, extends downward. A hand grip having an annular slidable element, enabling the hand grip to slide over the strong rod. The hand grip is attached to a brace that is an L shaped bar having a horizontal section and a vertical section, wherein the horizontal section of the L shaped bar provides support for the hand grip and the vertical section provides support for at least one vertical slide element. The horizontal section of the L shaped bar has a foreword opening through which passes the strong rod, extending rearward, wherein the vertical section overlaps at least one vertical slide rail.

In one variation, when the magazine release button on the firearm is pressed, the magazine is ejected, therein allowing the hand grip to drop to a lowered position. Similarly, the other vertical slidable components and the multi-magazine manifold all move downward when the magazine is ejected from the magazine well.

Another aspect of the apparatus is that it can include an automatic rotation mechanism to advance the multi-magazine manifold to the next magazine. The automatic rotation mechanism utilizes energy released when an empty magazine is ejected to rotate the multi-magazine manifold to the next magazine.

The apparatus can include a quick connect mechanism for attaching the multi-magazine manifold to the strut assembly.

DETAILED DESCRIPTION OF THE INVENTION

The invention is an apparatus that facilitates repeatedly aligning and loading a magazine into a magazine-well of a firearm, without the need for to visually disengage from a target. The apparatus includes a multi-magazine manifold which can hold a plurality of magazines, where the multi-magazine manifold is mounted to one or more vertical slides that with minimal assistance align a magazine with the magazine well. Ejection and reloading is faster and easier, as alignment is substantially built into the apparatus. The apparatus is rugged and simple to use, and can be fitted to a wide range of firearms.

The apparatus is conceptually illustrated in FIG. 1a-FIG. 1d and FIG. 2a-FIG. 2d, which are a series of side views of a firearm 100 fitted with the apparatus 10. The apparatus 10 is forward of the firearm's magazine-well 120 and mounted to the handguard rail 110. The firearm has a magazine ejection device 130 that releases magazines, causing them to be ejected from magazine-well. The apparatus provides a facile mechanism for repeatedly loading rounds from magazines 80,80′ bundled on a rotatable multi-magazine manifold 60 or on a semi-rotatable multi-magazine manifold 60′, and also a non-rotatable clamped multi-magazine manifold (not shown conceptually).

In the apparatus FIG. 1a-FIG. 1d the apparatus 10 has a semi-rotatable multi-magazine manifold 60′. The first vertical slide rail 30 extends downward from the adapter 20. The first vertical slide rail 30 is mounted to the handguard utilizing a handguard rail 110. The first vertical slide rail 30 has a first slidable element 40 with a strut assembly 50 extending from the first slidable element 40 to the semi-rotatable multi-magazine manifold 60′, wherein the magazine 80′, designated “0”, is attached to a side with a face 62′ of the semi-rotatable multi-magazine manifold 60′, and the “0” magazine is inserted in the magazine-well 120 of the firearm 100 and a magazine designated “X” is on the opposing side with a face 63′ of the semi-rotatable multi-magazine manifold 60′.

In FIG. 1b the “0” magazine has been ejected from the magazine-well, and the “0” magazine 80′ has dropped a distance sufficient to clear a rim 121 of the magazine-well 120, the movement of the “0” magazine has caused the first slidable element 40 to slide to a vertical slide full-stop element 32, which prevents further drop of the “0” magazine;

The semi-rotatable multi-magazine manifold 60′, as shown in FIG. 1c, has turned about 45 degrees of the 180 degrees necessary to flip to the next magazine 80, which is distinguished by the “X”. The semi-rotatable multi-magazine manifold 60′ has been flipped, as shown in FIG. 1d, therein aligning the “X” magazine 80 with the magazine-well 120 and, and the “X” magazine 80 has been pushed upward into the magazine-well 120, wherein the rounds can be chambered and the first vertical slidable element 40, the strut assembly 50 and the semi-rotatable multi-magazine manifold 60′ are back to the raised position on the first vertical slide rail 30.

The apparatus 10 with the rotatable multi-magazine manifold is shown in FIGS. 2a-2d. The action is mechanistically similar to FIG. 1a-1d except that rotation of the rotatable multi-magazine manifold 60 is into the page of a side view of the firearm 100. The mounting faces are numbered 62 and 63, dropping the apostrophe, indicating that the manifold is rotatable.

The rotatable multi-magazine manifold is a polygon having an axial center and having perimeter walls with magazine mounting faces, wherein a magazine mounting face can receive and hold a magazine utilizing a bottom end portion of the magazine, wherein each of the mounting faces can be fitted with one magazine.

In most cases it is anticipated that the apparatus will be used to align and load more than one magazine, and FIG. 3 illustrates an embodiment where the rotatable multi-magazine manifold 60 has five magazines. The illustrated rotatable multi-magazine manifold 60 is a pentagonal frustum polygon (a.k.a a polygonal frustum). Portions of the mounting faces 62,63,64 are visible in this perspective view. The two faces 65,66 not shown in FIG. 3 are shown in FIG. 11. The magazine-well 120 of the firearm 100 currently is filled with a magazine.

FIGS. 12a, 12b 12c and 12d illustrate several other, but not all, possible embodiments of rotatable multi-magazine manifolds that are similar suitable polygons. The polygons have an axial center and a plurality of perimeter walls, wherein the perimeter walls have external mounting faces. An external mounting face can receive and hold a magazine by a base portion of the magazine in potential alignment with the magazine-well, and when the manifold is filled the magazines are in radial alignment with the axial center.

Standard magazines nominally have an angled base to accommodate for the shape of the ammunition, and the illustrated polygonal frustums are similarly tapered to accommodate for the angle of the base of the magazine. For magazines having a substantially non-angled base, the polygon can be modified or selected to mount magazines with non-angled bases (not shown). Each rearward edge 61r of the frustum must have a length that is at least as long as a thickness 82t of a magazine, and each forward edge 61f frustum must be long enough that the taper matches the angled base 82a of the magazine, and also long enough to accommodate a width 82w of the magazine (see FIG. 11).

Each of the frustums illustrated in FIGS. 12a, 12b 12c and 12d is symmetrical, so that all faces on a given frustum are the same. The dimensions of the base and shape of a standard issue magazine was used to determine the size and shape of the manifold. The illustrated frustums are uniquely suitable for providing a multi-faced manifold. The practical range for a rotating manifold is up to six sides, as the frustum becomes overly large and once installed with loaded magazines, would be overly weighty above this for typical firearms.

Returning to FIG. 3, the adapter 20 includes a beam 22 with a set of fastening elements 24. The adapter provides an ultra-solid platform that won't slip even under heavy recoil, wherein the adapter is mounted to the handguard rail 110 forward of the magazine-well 120. The handguard rail is exemplified by a Picatinny and Weaver-style rails. The magazine ejection device 130 is nominally just rear of the magazine-well as shown in the illustrated embodiment. The first vertical slide rail 30 is a rigid structural member, wherein an upper end of the first vertical slide rail is mounted on the adapter 20 perpendicular to the beam 22. The lower opposing end is terminated with a full-stop element 32. The vertical slide rail functions as a guiding track to which a carriage can be secured. The first vertical slidable element 40 is supported and guided by the first vertical slide rail 30, wherein the first vertical slidable element 40 is gripping the first vertical slide rail 30 and functions as the carriage having a low resistance to moving along the first vertical slide rail 30 even when the first vertical slidable element is under stress, wherein the first vertical slidable element has a mountable surface that faces rearward toward the magazine-well 120.

The rotatable multi-magazine manifold 60 shown in FIG. 3 is a symmetrical polygonal frustum with an axial center 68 (see FIG. 11) and has five perimeter walls with magazine mounting faces 62,63,64,65,66. As shown in FIG. 11 the magazine mounting face can receive and hold a magazine utilizing a bottom end portion 82 of the magazine 80, wherein each of the mounting faces can be fitted with one magazine.

The rotatable strut assembly 50 has a strut 52, a positioning plate 51 with a plurality of set points 54 as shown in FIG. 3 and FIG. 4. In FIG. 3 a detent 55 can be seen that has a slightly protruding spring loaded ball (see FIG. 11a). The ball is aligned and partially seated in an opposing recess. In FIG. 4 the detent 55 is not aligned with any of the recesses 54 as the rotatable multi-magazine manifold is being rotated to the next magazine.

The strut 52 has a length selected to align a front exterior magazine side inside of an interior front magazine-well wall, and the set point for each of the magazine mounting faces is selected so that both magazine exterior side walls are aligned to fit inside the magazine-well. When the magazine ejection device 130 is actuated, the magazine in the well 120 is ejected causing the manifold 60, the rotatable strut assembly 50 and the first vertical slidable element 40 all to drop to their lowest position. The multi-magazine manifold can be turned to a next set point for the next magazine, and the next magazine is now positioned beneath and in-line with an empty magazine-well, wherein the next magazine can be shoved into the empty well. FIG. 5 illustrates the position of the next magazine just prior to being shoved into the magazine-well 120. Raising the magazine raises the manifold 60, the rotatable strut assembly 50 and the first vertical slidable element 40 to their upper operational position.

The apparatus 10 shown in FIG. 5 also illustrates a slidable grip assembly 70 that is mounted to the adapter 20 forward of the first vertical slide rail 30. The slidable grip assembly 70 includes a strong rod 72 mounted to the adapter 20. The beam 22 of the adapter 20 is extended to accommodate the slidable grip assembly 70, and the adapter has additional fastening elements 24 to attach the slidable grip assembly 70 to the handguard rail 110. The strong rod 72, which can support recoil, extends downward from the adapter 20. The slidable grip assembly 70 includes a hand grip 71 having an annular element 75 (shown in ghost as dashed lines), wherein the hand grip can slide over the strong rod 72. The annular element 75 is a core grip slidable element, for example a nylon bearing or a tubular element or ball bearings. There is a brace, which is an L shaped bar 73 having a horizontal section 73h and a vertical section 73v, wherein the horizontal section 73h of the L shaped bar provides support for the hand grip and the vertical section 73v provides support for at least one vertical slide rail. The horizontal section 73h of the L shaped bar has a forward opening 73o through which passes the strong rod 72 and rearward opening 74 that can accommodate the first vertical slide rail 30, the first vertical slidable element 40, and the second vertical slide rail 230 as shown in FIG. 7.

The L shaped bar 73 extends rearward overlapping the second vertical slide rail 230 and is attached to the second vertical slidable element 240, therein indirectly providing support for the second vertical slide rail 230. FIGS. 5, 6, 7, 8 and 9 illustrate the overlap of the vertical section 73v of the second vertical rail 230.

The second vertical slide rail 230, which is a rigid structural member, is mounted on the first vertical slidable element 40, and so when extended it only partially overlaps the first vertical slide rail 30. The second vertical slide rail 230 functions as a retractable extension of the first vertical slide rail 30. The vertical section 73v supports the second vertical slide rail 230 even when it is fully extended. The first and second vertical slide rail can be terminated with a second full-stop element (not shown) to ensure that the first and second vertical slidable elements remain on their corresponding vertical slide rails.

In FIG. 7 the illustrated apparatus 10, which has a second vertical slide rail 230, also has an adjustable resistance element 236 that prevents the second vertical slidable element 240 from moving as fast as the first vertical slidable element 40. This is particularly important when the apparatus 10 also has an automatic rotation mechanism 90 that advances the rotatable multi-magazine manifold 60 to the next magazine, as rotation should only commence after an ejected magazine has cleared the rim 121 of the magazine-well 120 as shown in FIG. 5. The automatic rotation mechanism 90, is only barely visible in FIG. 7 and FIG. 6, except for a latch 94 and a partial view of a geared cocking round lever 92. The side view in FIG. 8 and FIG. 9 provide more detail. The automatic rotation mechanism is described in greater detail below.

Recapping, the apparatus in FIG. 3 and FIG. 4 had only a single vertical slide rail 30. In FIG. 5, the addition of the grip assembly expanded the number of vertical slide rails to include a second vertical slide rail 230, where the second vertical slide rail is attached to the first vertical slide rail via first vertical slidable element 40. When there was one vertical slide rail (FIG. 3 and FIG. 4) the strut assembly 50 was mounted on the first vertical slidable element 40. When there is a second vertical slide rail 230, the strut assembly 50 is mounted on a second vertical slidable element 240. In FIG. 6, FIG. 7, FIG. 8, and FIG. 9 illustrate more detail about the apparatus, as the apparatus is not mounted, and further expand on the elements of the automatic rotation mechanism.

The apparatus is illustrated in FIG. 8 in the raised ready position, and in FIG. 9 in the lowered, rotatable position. In the raised position the upright magazine 80 normally is in the magazine-well. In the illustrated embodiment the apparatus 10 includes a slidable grip assembly 70 mounted to the adapter 20 forward of the first vertical slide rail 30. A strong rod 72 extends vertically downward from the adapter 20. The fastening elements 24 attach the beam 22 of the adapter 20 to a handguard rail 110 (FIG. 5). Three bolts and nuts are shown for securing the adapter 20 to the to the handguard rail. The slidable grip assembly 70 and the first vertical rail 30 are structurally secured to an underside of the beam 22. The L shaped bar 73 is a strength element and is vertically slidable. The brace, an L shaped bar has a horizontal section 73h and a vertical section 73v, wherein the horizontal section 73h of the L shaped bar provides support for the hand grip and the vertical section 73v provides support for at least one vertical slide rail. The annular element 75 provides the grip with a hollow core enabling both the grip and the horizontal section 73h it is attached to move vertically. As shown in FIG. 7, the forward opening 73o can slide over the strong rod 72 and the rearward opening 74 that can accommodate the first vertical slide rail 30 and the first vertical slidable element 40.

The second vertical slide rail 230 is fastened to a rearward facing mounting plate of the first vertical slidable element 40. As previously noted, the horizontal section 73h of the L shaped bar of grip assembly 70 has a forward opening 73o through which passes the strong rod 72 and rearward opening 74 that can accommodate the first vertical slide rail 30 and the first vertical slidable element 40 as shown in FIG. 7. In the fully raised position (see FIG. 6), the first vertical slidable element 40 is located substantially under the horizontal section 73h. Compare the relative positions of the first vertical slidable element 40 in FIG. 6 and FIG. 7 with respect to the horizontal section 73h. In FIG. 7 the first vertical slidable element 40 protrudes upward through the opening 74.

The strut assembly 50 includes the automatic rotation mechanism 90, as shown in FIG. 10. The automatic rotation mechanism advances the rotatable multi-magazine manifold 60 to the next magazine, when the magazine in the magazine-well is ejected. The automatic rotation mechanism 90 harvests energy released when the magazine is ejected to increment the rotation. The amount of rotation is in a number of degrees as a fraction of a circle, where the number is 360 degrees divided by the number of magazine mounting faces. In the case of a pentagon, an increment of rotation is seventy two degrees (360/5=72). The automatic rotation mechanism harvests most of the energy released when the magazine is ejected to rotate to the next magazine, and as will be seen some this energy is recaptured when the next magazine is loaded into the magazine-well 120 of the firearm 100.

A side view of the apparatus 10 is shown in FIG. 8, where the pentagonal multi-magazine manifold is raised and, as shown, an upper magazine would be in the magazine-well. The adapter 20 has a beam 22 and additional fastening elements 24. The grip assembly 70 has a grip 71, which slides over the rod 72. Dashed lines suggest the grip's core annular element 75. Dashed lines also are used to suggest openings 730 and 74.

The second slidable element 240 has rearward mounting plate 244 to which is mounted the strut assembly 50. The strut has an axial plate 51 for mounting the strut to the rotatable multi-magazine manifold 60. Elements of the automatic rotation mechanism (see FIG. 10) are only partially visible. They include a geared cocking round lever 92 on the strut 50 and a latch 94 mounted on the second vertical slide rail 230. A covering plate 245 protects the many of the elements of the automatic rotation mechanism.

In FIG. 9 the apparatus has been lowered. The first vertical rail 30 is extended with a second vertical rail 230. The second vertical slide rail 230 is capped with an upper stop 237, and is mounted on the first vertical slidable element 40. The second vertical slide rail 230 functions as a retractable extension of the first vertical slide rail. The chamber end 81 of the magazine 80 feeds into the magazine-well. The L shaped bar 73 has an opening 74 (indicated by dashed lines) that permit the L shaped bar 73 to move past the first vertical slide rail 30 and the first vertical slidable element 40.

Rotation should not begin until the magazine has cleared the rim 121 of the magazine-well (see FIG. 5). The operative elements of one embodiment of the automatic rotation mechanism 90 are described in FIG. 10 and FIG. 10a. It is anticipated that other mechanisms are possible, for example those that use one-way bearings, and in disclosing this embodiment the concept is taught.

When a magazine is ejected from the magazine-well the first vertical slidable element drops carrying the second vertical slide rail to its extended position. The second vertical slidable element 240 is somewhat restrained, and it slides from its raised position, defined by an upper stop element 239 (see FIG. 10 and FIG. 10a) for the second vertical slidable element 240, and slowed by an adjustable restraint element 236, for example an adjustable detent, giving enough time for the magazine to clear the magazine rim before activating the automatic rotation mechanism. The automatic rotation mechanism 90 is shown in FIG. 10 as a series of views from left to right as seen from the manifold 60.

When a magazine is loaded into a magazine-well the upper stop element 239 using the slidable grip assembly 70, the second vertical slidable element is moved upward until it abuts the upper stop element 239, wherein the second vertical slide rail 230 is raised, collapsing the second vertical slide rail 230 on top of the first vertical slide rail 30, shortening the overall length of the extendable piggybacked rails.

The second vertical slidable element 240 starts sliding down the second vertical slide rail 230 almost immediately when the current magazine is released. It is slowed slightly by the adjustable restraint element 236. The second vertical slidable element 240 has a front protective plate 244, that is protects the automatic rotation mechanism 90. An axial rod 92b projects rearward from the front protective plate 244, and it functions as a bearing for a geared cocking round lever 92 and is coaxial with the strut 50, wherein the strut 50 can rotate on the axial rod 92b. The geared cocking round lever 92 is mounted on the strut. The geared cocking round lever 92 has scalloped gears 92a. A spring loaded latch 94 having positively scalloped gears 94a and an abutting straight section 94a′ is mounted to the second vertical slide rail 230. The positively scalloped gears 94a are selected to mesh with the scalloped gears 92a, but the gears are skewed so as to induce more tangential force in one direction and slippage in the opposing direction.

FIG. 10a shows detent 250 on the rail side of the second vertical slidable element 240 that is mated with adjustable resistance element 236 when the magazine is chambered inside the magazine well. As shown in FIG. 10a the spring 95 of the spring loaded latch 94 has a coil 95a that is centered on the pivot pin 97, a hook 95b that loops around a peg 91 projecting from the second vertical slide rail 230, and a piercing pin 95c that projects through the latch 94 through a pin opening 93. Rotation of the latch is limited by peg 91 against a start notch 94d and a stop notch 94b. Prior to contact of the geared cocking round lever 92 with the spring loaded latch 94, the spring loaded latch is nearly upright, with the peg 91 seated in the start notch 94d. When the lever 92 contacts the latch 94, it initially is with an abutting straight end section 94a′ of the latch as shown in the second of the series of seven views. The meshing produces a tangential force on the on geared cocking round lever 92, causing it to rotate clockwise. The latch responds by swinging counterclockwise 99, exposing additional positively scalloped gears 94a, which cause further clockwise rotation 98 of the lever. Rotation ceases when the stop notch 94b rests against the peg 91, as shown in the last view of the series. The swing action tensions the coiled spring 95. The next magazine is now aligned, ready to be moved into the magazine-well. Loading is performed by simply raising the slidable grip assembly 70, if available, or gripping the manifold or a magazine on the manifold to move the aligned magazine into the well. The weight of the apparatus can be used to load the next magazine by lifting the firearm upright or even inverted, as alignment is maintained.

Raising the geared cocking round lever 92 does not mesh gears as the spring loaded latch just rides over the lever's gears 92a, consequently there is no additional rotation. FIG. 11a further clarifies the mechanism. Additionally as shown in FIG. 11a, when the desired rotation is achieved a detent on the second vertical slidable element 240 clicks into place once the cocking round lever 92 has rotated the desired number of degrees.

In FIG. 11a, frontal face 60f of the rotatable multi-magazine manifold 60 has an alignment cog 68a along an edge of the axial opening 68 to a central bore 902 of the rotatable multi-magazine manifold 60. The central bore 902 allows axial rod 92b to pass into the rotatable multi-magazine manifold's central bore 902, and fit into slots (not shown) on the axial positioning plate 51 to ensure proper positioning of rotatable multi-magazine manifold 60 with the magazine well. The rearward face 60r of the rotatable multi-magazine manifold has a quick release 900, which when compressed, retracts retaining balls 901 out of expansion chamber 903 of bore 904 in axial rod 92b and allows easy removal of the entire rotatable multi-magazine manifold. FIG. 1la also shows detents 54 in a geared cocking round lever 92 that correspond with adjustable resistance element 54 on the partially cut-away second vertical slidable element 240 so that when geared cocking round lever 92 has rotated the correct incremental number of degrees, the spring decompresses to fill detent 55 and prevent further rotation clockwise or counterclockwise so the magazine is properly aligned with the magazine well.

The tensioned coiled spring 95 returns the latch 94 to its upright position as shown in the first view and second view of the series. Only, after the next magazine is ejected will rotation again move the next incremental number of degrees. The automatic rotation mechanism 90 harvests the energy released during ejection to power the automatic rotation mechanism, conserving some energy with the coiled spring 95.

FIG. 11, 11a, and FIGS. 12a-12d have previously been discussed.

A variation of the apparatus 10 is illustrated in FIG. 13, wherein the apparatus has a semi-rotatable multi-magazine manifold 60′. The semi-rotatable multi-magazine manifold 60′ provides rotation through only 180 degrees. As will become clear, the magazines are mounted on the semi-rotatable multi-magazine manifold 60′ having a face that is angled when positioned on a semi-rotatable strut assembly 50′ to compensate for the angle of the base of the magazine. The magazines are still aligned with the magazine-well, and the manifold 60′ rotates in the plane of the paper, as was conceptually described in FIGS. 1a-1d. The semi-rotatable manifold makes it possible to repeatedly load and eject multiple magazines without visually disengaging from a target.

In the illustrated semi-rotatable embodiment of the apparatus the adapter 20 is mounted directly to a handguard or as illustrated to a handguard rail 110 of a firearm 100. As illustrated in FIG. 13 the apparatus includes an adapter 20, a mounting block 310, and a horizontal slide rail 330 that is mounted on the mounting block 310 at right angles to the adapter. The horizontal slide rail 330 has a horizontal slidable element 340 that can slide across a rearward side of the horizontal slide rail 330. A first vertical slide rail is rigidly attached to the horizontal slidable element 340. The first vertical slide rail 30 has an overlapping second vertical slide rail 230 that functions as an extension of the first vertical slide rail 30. The second vertical slide rail 230 is mounted on a first vertical slidable element 40. The second vertical slide rail 230 has a second vertical slidable element 240. The vertical slide rails and vertical slidable elements are jointly referred to as a vertical slide rail assembly. Movement of the horizontal slidable element 340, and the affixed vertical slide rail assembly is in the Z-plane, which is in-to or out-of the page of the side view of the apparatus relative the firearm.

The horizontal slide rail has one or more Z-plane stopping points that the horizontal slidable element can be moved, where a number Z of stopping points nominally matches the number of blocks included in a semi-rotatable multi-magazine manifold 60′. See FIGS. 21a-21d for examples of semi-rotatable multi-magazine manifold 60′ having a plurality of blocks 62′. Each Z-plane stopping point is selected so that at least one of the magazines affixed to a block on the semi-rotatable multi-magazine manifold is spatially aligned between a right side and a left side of a magazine-well. In FIG. 13 there are three blocks 62a′,62b′,62c′, so there are three stopping points on the horizontal slide rail. The stopping points 331a, 331b, 331c are not visible in FIGS. 13 and 14, but they are shown in other drawings. The two outboard stopping points 331a and 331c are shown in FIG. 18b, and the center stopping point 331b is shown in FIG. 22.

The semi-rotatable strut assembly 50′ is mounted on a rearward face of the second vertical slidable element 240. The illustrated semi-rotatable strut assembly 50′ has two struts a left strut 52l′, and a right strut 52r′. The struts are parallel and have a length that is selected so that the semi-rotatable multi-magazine manifold has at least one magazine affixed to a block that is spatially aligned front-to-back with the magazine-well 120. In general the strut assembly 50′ has one less strut than there are blocks 62′. A maximum of five blocks 62′ is anticipated, due to the practicality of size and weight limits for maneuverability of the firearm, so a maximum of four struts are anticipated, however, theoretically, these numbers are not finite.

FIGS. 21a-21d illustrate semi-rotatable multi-magazine manifolds 60′ having a plurality of blocks 62′, where the plurality is two to five blocks (62a′ & 62b′) up to (62a′ & 62b′ & 62c′ & 62d′ & 62e′). All the manifolds have a pair of connecting rods 681′, 682′ and one axle 64′. All the blocks of the different manifolds are separated by spacers 691′. Each block has opposing mounting faces. For example FIG. 21b has six mounting faces 621′ (see FIG. 18) and 622′, 623′ (see FIG. 18) and 624′, 625′ (see FIG. 18) and 626′.

FIG. 22 provides an example of a stopping point 331b′ on the first horizontal slide rail 330 is. The slidable horizontal slidable element 340 has a recessed depression 341 that can receive a detent 331b′ that is press fitted in the horizontal slide rail 330. The slidable horizontal slidable element 340 could alternately be fitted with the detent, but the downside is that the slidable horizontal slidable element 340 would not move as easily between points, and the change in drag/friction between points is smaller and therefore not as easily detected. In the current embodiment, the horizontal slide rail is fitted with three detents instead of one in the slidable horizontal slidable element 340 provides a more pronounced stop, and there is less wear, therein assuring alignment of a magazine on the manifold with the magazine-well.

In FIG. 13, there is currently a magazine 80 is in the magazine-well 120. The current magazine is ejected by simply actuating the firearm's magazine ejection device 130, which is more clearly seen in FIG. 14. In FIG. 14 the current magazine has been ejected causing the magazine on the semi-rotatable manifold, the semi-rotatable strut assembly and the vertical slide rail assembly to drop. To load the next magazine into the empty magazine-well the semi-rotatable manifold 60′ is either flipped to the opposing magazine or the vertical slide rail assembly is shifted to a new stopping point by sliding the horizontal slidable element 340, therein moving the manifold inboard or outboard, and then shoving the aligned magazine into the magazine-well. FIG. 14 shows the apparatus immediately following ejection.

FIG. 15 illustrates the semi-rotatable multi-magazine manifold 60′ in the process of being flipped. The magazines labelled “R”, “C”, “L” that were previously shown in FIG. 14 have been turned about 90 degrees. They must be turned a full 180 degrees, so that the three magazines that were on the top-side and righted are rotated to a bottom-side, where they are inverted and reversed. Whether rotation is clockwise or counter-clockwise is determined by the manifold 60′ current position, as rotation between the struts is not allowed. As show in FIG. 18 and FIG. 19, the blocks 62′ making up the manifold 60′ are held together with connecting rods 681′, 682′ on opposing sides of a center axle 64′. The blocks are separated by spacers 691′, 692′, 693,′694′. The rods and spacers prevent rotation between the struts, and in fact they act as stopping elements. As shown in FIG. 18, the struts 52l′,52r′ have top-side grooves 591′,′593′ can only receive the top-side spacers 691′,693′, and the bottom-side grooves 592′,594′ can only receive the bottom-side spacers 692′,694′. So, if the manifold 60′ as shown in FIG. 19 is positioned with the top-side spacers 691′,693′ in the top-side grooves 591′,′593′, then flipping is only possible if the rotation is clockwise. Of course, if the bottom-side spacers 692′,694′ are in the bottom-side grooves 592′,594′ then only counter-clockwise rotation is possible.

After flipping potentially all the now top-side magazines can be chambered into the magazine-well, one will be aligned. The other now top-side magazines can be chambered by shifting the horizontal slidable element on the horizontal slide rail to either a center position or either of the two outer positions, where each position is in alignment with the magazine-well 120. The manifold is raised, loading the selected magazine into the magazine-well.

FIG. 16a illustrates the apparatus shown in FIG. 13 without the firearm. FIG. 16b illustrates the apparatus shown in FIG. 14 without the firearm, and FIG. 16c illustrates the apparatus shown in FIG. 15 without the firearm. The most notable feature is that while the magazines and the vertical slide assembly are parallel, the blocks 62a′,62b′,62c′ are angled so that the face when the standard magazine 80 is mounted it has a vertical orientation. This is easier to see in FIG. 17. The angle of block 62c′ is selected so that the face 643′ compensates for the angle of the base 82, which is often slopped. The slope angle is 82a. This is a real advantage, as a user can use standard magazines on the semi-rotatable multi-magazine manifold 60′, or if the base is not not-angled, the manifold can be selected for a non-angled base.

In the embodiment illustrated in FIG. 18 and FIG. 18a the left strut 52l′ and the right strut 52r′ each have a bearing 53l′,53r′ with a gap 54l′, 54r′, wherein the semi-rotatable multi-magazine manifold 60′ has a quick connect axle 64′ (as shown in FIG. 18ba and FIG. 18b) that can be fitted within the semi-rotatable multi-magazine manifold 60′. The quick connect axle 64′ enables the semi-rotatable multi-magazine manifold 60′ to be positioned on the struts, with the axle 64′ mounted in the bearings 53l′,53r′. No disassembly of the bearings or the manifold is required.

Also in FIG. 18, all six mounting faces are numbered 621′, 622′, 623′, 624′, 625′, 626′. Three of the faces are marginally visible. Each mounting face can be fitted with a magazine, as shown in FIG. 17 and others. There are a total of six magazines. In other variations the manifold shown in FIG. 21a could hold four magazines; in FIG. 21c could hold eight magazines; and the manifold in FIG. 21d could hold ten magazines. Typically, the magazines hold twenty or fewer rounds of ammunition. The magazines illustrated in FIG. 17 are a ten round clip, which is atypical, but gaining in usage. As shown in FIG. 18 and to a lesser extent FIG. 20, the block polygons 62a′, 62b′, 62c′ share a spring loaded quick connect axle 64′, and are equally spaced by hollow spacers 691′,692′,693′,694′ through which extend connecting rods 681′, 682′ that are threaded headed pins. As previously discussed, the spacers are positioned to also function as stops, when the semi-rotatable multi-magazine manifold 60′ is flipped.

As can be seen in FIG. 18 the axle 64′ is keyed so that when properly positioned slots 641′ and 642′ can pass through the bearing gaps 54r′ and 54l′ as shown in FIG. 18a and FIG. 18b. As diagrammatically illustrated as a sequence of views in FIG. 18a this is possible only when pressure is applied to axle button 643′, compressing the compression spring 65′, which aligns the slots 641′, 642′ with the bearings slots 53r′ and 53l′. As soon as pressure is released, the compression spring expands 65′, the axle shifts, the slots and gaps are no longer aligned, and the axle 64′ is retained because the bearings see the full diameter of the axle. To achieve this, each of the blocks 62a′, 62b′, 62c′ has certain features.

FIG. 20 is a diagonal cross-section of the semi-rotatable multi-magazine manifold 60′ without the quick connect axle 64′ shown in FIG. 18. The center block 62b′ has a centroid bearing bore 63b′. A center section of the axle 64′, where the center section is the sectional length between slots 641′ and 642′ (as shown in FIG. 18) is substantially housed in the centroid bearing bore 63b′. The center block 62b′ also has a pair of through-block openings 633′ and 634′ for the connecting rods 681′ and 682′. The diameter of the opening 633′ is sufficiently small to occlude the spacers 693′, 694′. The right block 62a has a partial centroid end-bearing bore 63a′ with a floor 64a′, wherein a centroid partial bore 63a′ can receive the spring 65′ and an end of the axle 64′. The right block 62a′ has threaded holes 631′ and 632′ the connecting rods 681′ and 682′ having threaded sections 671′,672′ (see FIG. 18). A left block 62c′ has a centroid bore 63c′ that narrows to a constricted bore 64c′ that stops the axle but allows a button 643′ (see FIG. 18) to project through and out the side of block 62c′. The axle 64′ is largely centered in the centroid bearing bore. An exception is when pressure is applied to the button causing the compression spring 65′ to be compressed, therein shifting the shaft toward the right block 62a, aligning the slots 641′, 642′ with the bearings slots 54r′ and 54l′. Without compression, the manifold is retained by the bearings 53l′,53r′.

To achieve the desired slope angle is 82a angle there are several factors to consider including the distance of the connecting rods from the axle, the proximity of the connecting rods to a block's face, the diameter of the spacers, and the location of the strut bearings. As shown in FIG. 18 and FIG. 19, the slope angle is relative shallow, and the bearings 53l′,53r′ are substantially proximate to a lower side of the struts 52l′, 52r′.

The horizontal slide rail 330 and the horizontal slidable element 340 is shown in more detail in FIG. 22. In the embodiment the mounting block 310 is coextensive with the adapter. The horizontal slide rail 330 is fastened to the mounting block with at least two screws 15a, 15b. Only screw 15a is shown, as a portion of the mounting block is cutaway to see the horizontal slide rail 330. In general, the slidable elements are not limited to a specific type of bearing to minimize friction, as multiple factors can enter in the determination. Encapsulated ball bearings and bushings are two types that are commonly employed. In the illustrated horizontal slidable element ball bears are shown, but bushings or self-lubricating systems can be employed.

The horizontal slide rail 330 has a pair of opposing channels, an upper channel 333a and a lower channel 333b. The horizontal slidable element 340 nominally has a set of race of ball bearings upper race 343a and lower race of ball bearings 343b. The upper race 343a is not visible because a portion of the horizontal slidable element 340 is cut away to show the first vertical slidable rail 30. The vertical slidable rail 30 is fastened to a rear side of the horizontal slidable element 340 using screws 345b and 345a. The top screw 345a is not visible as the upper portion of the horizontal slidable element 340 is cut-away. An upper portion of the vertical slidable rail 30 has a threaded hole 36a that receives the top screw 345a in an upper portion of the horizontal slidable element (not visible). The lower portion of the vertical slidable rail 30 is obscured by the horizontal slidable element 340, and so a threaded hole 36b is not visible.

The first and second vertical slidable rails 30,230 also have a pair of opposing channels 33, 233. The first and second vertical slidable elements 40,240 have would similarly have their own set of race of ball bearings. The second vertical slidable element has a plurality of holes 243 for fastening the semi-rotatable strut assembly 50′ (not shown).

An apparatus with a non-rotating strut assembly 150 and a non-rotatable multi-magazine manifold 160 is illustrated in FIG. 23. There are three higher round count magazines. Several rounds 85 are visible. A higher count magazine holds more than ten rounds, and usually twenty or more rounds. The non-rotating strut assembly 150 has a left prong 152 and right prong 154. The non-rotatable multi-magazine manifold 160 has a forward flat bar 162, a rearward flat bar 164, and spacing elements 165, 166 between the magazines. The forward clamp 162 is attached to the left prong 152 and right prong 154. The forward flat bar 162 has a pair of lateral tabs (only left tab 1621 is shown), and the rearward flat bar 164 has a pair of lateral tabs, where only 1641 is visible. The width of the spacing elements 165, 166 matches distance between stopping points 331a,331b,331c (not visible in this view-see FIG. 18b and FIG. 22). As shown there is a center magazine 180b, a left magazine 180c, and a right magazine 180a. The magazines form a stack 180. As previously disclosed the apparatus has a horizontal slide rail 330 with a first horizontal slidable element 340 that provides the capability to shift the non-rotatable multi-magazine manifold 160 to another stopping point, when the vertical assembly is lowered. The first horizontal slide rail 330 is attached to the adapter 20 via the mounting block 310. The first vertical slide rail 30 with a piggy-backed second vertical slide rail 230 via a first vertical slidable element 40. The second vertical slidable element 240 has rearward facing plate to which is mounted the non-rotating strut assembly 150. A magazine is selected by moving to a stopping point. Magazine 180b is shown loaded in the firearm's magazine-well 120.

The apparatus as illustrated in FIG. 24 has a quick release slide lock (QRSL) 800 that enables attaching and detaching a modified non-rotatable multi-magazine manifold 168, where components of the QRSL 800 are fitted on the non-rotating strut assembly 150 and the non-rotatable multi-magazine manifold 160 that provide for changing manifolds. The modified forward flat bar 162 of the non-rotatable multi-magazine manifold is fitted with a plurality of studs 872 that project forward. Three studs are shown, and each has a beveled end and a setback circular groove. A spring loaded sliding plate 835 forwardly overlaps a latch base plate 825. The spring loaded sliding plate 835 (see FIG. 26b) has a plurality of elongate holes and each hole has a headed stem 855 that is projecting from the latch base plate 825. The spring loaded sliding plate 835 has a plurality of semi-circular edges, and the semi-circular edges are abutting the setback circular grooves of the studs 872, therein latching the non-rotatable multi-magazine manifold 160 to the non-rotating strut assembly 150.

In FIG. 25 the modified non-rotatable multi-magazine manifold 168 is disconnected from the strut assembly fitted with the quick release slide lock 800. A little more detail is viewable. The beveled studs 872, mounted on the forward clamp bar 162 of the non-rotatable multi-magazine manifold, have a relatively high aspect of bevel 873, so that they are capable generating a lateral penetrating force, enough force to widen an iris-like opening. The circular groove 874 is substantially at the perimeter of the bevel 873. The lock 800 is in the default locked position, with openings 837 partially closed, a QRSL button 845 on the spring loaded sliding plate 835 shifted outboard, where it is pushed inboard to open the lock. The a set of headed stems 855 are inboard of a set of two elongate holes (see FIG. 26a), limiting a distance that the spring loaded sliding plate 835 can move outboard, therein controlling a diameter of the partially closed openings 837.

A closer view of the quick release slide lock 800 is shown in FIG. 26a. The QRSL is in the locked position, which is the default position, wherein three beveled studs 872 are projecting through the QRSL, where each stud 872 has a circular groove 874 (see FIG. 25) that is proximate to the perimeter of the bevel 873, and each stud is long enough to extend through the QRSL, which has the spring loaded sliding plate 835 that forwardly overlaps the latch base plate 825 which has a set of larger diameter holes 838. The spring loaded sliding plate has a lower edge that includes a curvilinear section of a smaller diameter semi-circular segment 839 contiguous with a larger diameter semi-circular segment 837, which, when moved laterally outboard, the curvilinear section intersects a stud 872, and more particularly the circular groove 874 proximate to the perimeter of the bevel 873. Taken together the curvilinear sections of the sliding plate and the larger diameter holes 838 of the latch base plate lock the stud. The prongs 154,152 are shown is ghost by the dashed lines. Fastening holes 854 are for attaching the latch base plate 825 to the prongs 154,152.

The quick release slide lock (QRSL) is shown unlocked in FIG. 26b. The unlocked—release position is produced when the QRSL button 845 is pressed, causing the spring loaded sliding plate to move inboard, wherein each of the studs 872 will be disengaged, therein enabling the modified non-rotating multi-magazine manifold to be removed.

Finally, any numerical parameters set forth in the specification and attached claims are approximations (for example, by using the term “about”) that may vary depending upon the desired properties sought to be obtained by the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of significant digits and by applying ordinary rounding.
